/* Pthread (-ish) rwlock

 *

 * This differs from normal pthreads rwlocks in two ways:

 * 1. Separate APIs for releasing read locks and write locks (as

 *    opposed to the pure POSIX API which only has one unlock fn)

 * 2. You should not use recursive read locks (i.e. grabbing a read

 *    lock in a thread that already holds a read lock) because the

 *    Windows implementation doesn't support it
